AbstractIn the context of ultraviolet-laser sculpting of the cornea to achieve optical correction through a newly shaped anterior surface, the invention subjects the laser beam to certain shaping and homogenizing operations prior to any attempt to specially characterize the beam for a particular sculpturing procedure. In a preferred embodiment, the shaping and homogenizing operations present a tolerably homogeneous beam of enlarged dimension, so that specialty-characterizing may proceed on a dimensional scale that is greater than the corresponding dimension of ultimate surgical delivery to the eye, thereby enabling greater control of the quality of specialty-characterizing. Provision is made for selectively monitoring the quality of the homogeneity and/or of the specially-characterized beam, with further provision for automated cutoff of laser beam delivery to an eye in the event that quality is not within predetermined limits of tolerance. And preferably, all beam shaping, homogenizing and characterizing operations proceed in a controlled environment which precludes ozone development and thus minimizes the beam-degrading effect of ozone and particulates or other contaminants.Other References
